The first presentation video with the Cadillac XTS Platinum Concept has been released by GM, after the luxurious sedan has its world premiere at the 2010 Detroit Auto Show.

The Cadillac XTS Platinum will enter the automotive scene as a direct competitor to the Mercedes S Class, BMW 7 Series and Audi A8 and will feature a 3.6 litre V6 gasoline powering unit with Direct Injection, together with a plug-in hybrid system.

As the Cadillac XTS Platinum Concept has just debuted we do not know if this will be the only powering option available for the production version, or if 350 HP and 400 Nm of torque packed by the show car presented in Detroit will be enough to compete with its rivals.
